In his Medium column, Ryan wrote that a new direction was needed on government anti-poverty efforts.

"We’ve been fighting the War on Poverty for 50 years now," he wrote. "And I don’t think you can call it anything but a stalemate. The federal government has spent trillions of dollars. And yet today, if you were raised poor, you’re just as likely to stay poor as you were 50 years ago. I’m not saying we haven’t made progress. We have. But today we have a safety net that catches people falling into poverty. What we need is a safety net that lifts people out of poverty – that helps them earn a good paycheck so they can support themselves."

Here, we’ll check Ryan’s statement that "today, if you were raised poor, you’re just as likely to stay poor as you were 50 years ago."

The paper, based on extensive analysis of income and educational-attainment data, found that "intergenerational mobility" has "remained extremely stable" since the generation of Americans born in 1971.

"We find that children entering the labor market today have the same chances of moving up in the income distribution (relative to their parents) as children born in the 1970s," the authors wrote.

When we asked one of the co-authors, Saez, whether Ryan’s summary left out anything important, he said no.

"Yes, this is broadly correct," Saez told PolitiFact. Saez said the paper shows the odds of staying in the bottom one-fifth of the income distribution when your parents were in the bottom one-fifth have stayed stable for the past four to five decades.

The paper and Saez in the interview both noted one caveat – that the consequences of the pattern Ryan is citing have worse effects today because inequality has grown over the same period.

"Because inequality has risen," the paper notes, "the consequences of the ‘birth lottery’ – the parents to whom a child is born – are larger today than in the past."

However, this caveat doesn’t undermine Ryan’s point. If anything, it accentuates it. (We're also not penalizing Ryan for rounding up the study's length to 50 years.)

Tara Sinclair, a George Washington University economist and chief economist at the jobs site Indeed, said the paper Ryan chose is a credible one within the profession. "These are the authors I would turn to" when looking at intergenerational mobility.

Our ruling

Ryan wrote that "today, if you were raised poor, you’re just as likely to stay poor as you were 50 years ago." His support for this claim – a respected academic paper published in 2014 – found exactly what Ryan described. We rate the claim True.
